AleksandrR [38]

Answer:

x²- √3 x +1/2

Step-by-step explanation:

To write a quadratic equation with roots only:

x² -(sum of the roots)x+(product of roots)

x²-((√3-1/2)+(√3+1/2)x + ((√3-1/2)(√3+1/2)

x² -(2√3)/2 + ( 9-1)/4

x²- √3 x +1/2

3 / 5 = (x+1) / (y-2)
↓
↓ multiply by 5 / 3
↓
1 = 5 * (x+1) / 3 * (y-2)
↓
↓ move and simplify
↓
5x + 5 = 3y - 6
↓
↓ minus 5
↓
5x = 3y - 11

What is the distance between each pair of points (-3,3),(5,0)

Effectus [21]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (-3, 3) and (5, 0).

Substitute the coordinates of the points to the formula:

$d=\sqrt{(5-(-3))^2+(0-3)^2}=\sqrt{8^2+(-3)^2}=\sqrt{64+9}=\sqrt{73}$
